DUMP-CAR DUOR LOCK.

Application filed September 2, 192a seri l no, 133,237.

after described and claimed, the description being supplemented by the accompanying drawings.

Figure 1 is a side elevation showing the application of the invention, the door 01" a dump pocket being held in closed position.

by such invention, in this view.

Figure 2 is a horizontal sectional view on line 2-2 01 Figure 1.

Figure 3 is'an elevation asindicated by line 33 of Figure 1.

Figure d is an enlarged side elevation showing the manner of releasing the looking means to permit opening of the door.

Figure 5 is a detail horizontal section on line 5-5 of Figure 41.

Figure 6 is a perspective view of the bracli'et upon which all movable parts are mounted.

Figure 7 is a perspective view of the shaft upon which the doorlocking wheel and the ratchet wheel, yet to be described, are secured. p

The construction herein disclosed may be considered as preterredand while this construction will be rather specifically described, it is to be uuderstoot at the outset,

that within the scope of the invenion as claimed. numerous variations may be made.

The numerals 8 and 9 designate two flat substantially horizontal arms disposed in spaced parallel relation and having attachingplates 10 and 11 at one end, the arm 9 being offset near its end as indicated at 12. to dispose its attaching plate 11 in contact with the plate 10. These plates are formed with aligned openings to receive rivets 13 or other fasteners, for securing the bracket structure (formed by the parts so far dealt with) to the exterior of one of the dump pockets P of a dump car. I) designates the usual downwardly swingable door of the pocket. r

The free endsof the arms 8 and 9are formed with axially aligned openings 14 whose commonaxis is at right angles to the plane of the plates 10 andll. In these openings, a short, heavy. shaft 15 is rotatably mounted, the outer end of this shaft being provided withprojectingstuds 16 for engagementiwith a suitable'b ar so. that the shaft may be forcibly rotated in one direction, and thisrotation will efiect tight, final closing of the door D, as will hereinafter appear.v V

T he outer ends of the studs 16 are formed with heads 17, and at theinner end of these studs, the shaft 15 is provided with cams 1S. Thesegcams, eliect outward forcing of the above named bar as it is being operated to turn the shaft and so wedge said bar against the heads 17, as to prevent slippage 7 thereof. H r

A door-locking wheel 19 and a ratchet wheel 20 are fixedlysecured to the shaft 15, by a key 21 and appropriate key-ways 22, or by other desired means. The wheel 19 is provided with a plurality of'circumferentially spaced, peripheral teeth 23 which are adapted to engage the projecting end o1"- a bar B, secured to the door I), as will be clear from Figures 1 and 1. ,After initial engagement of the bar end with teeth of the wheel 19, rotation of this wheel inthe proper direction will cause tight closing of the door D. A, suitable dog 24 is carried by the bracket structure and cooperates within c ratchet wheel .20 inv holding the wheel 19 againstretrograde rotation, so as to cause said wheel to tightly lock the dooriniclosed position. Preferably, apivoted safety lock 25-is provided tosecure the dog 24 in operative position after finalclosiiig of the door D. In the present disclosure, thearm .9 is formedfwith an upwardly projectinglugQS upon which the dog and the safety lock are pivoted, the pivots of these parts are being designated 27 and 28 respectively.

The free end of the dog 24- is provided with a projecting headed stud 29 to be engaged by a bar which is shown by the dotted lines 30 in Figure 4:. The arm 9 is provided with an appropriate shoulder 31 to engage the inner end oi -this bar so that the latter may be effectively used as a lever to release the dog 24:, after first releasing the safety rotated. During this rotation, the teeth of the wheel 19, being engaged with the bar B, effect tight closing of the door D, and the dog 24; and ratchet wheel come into play to hold said wheel 19 against retrograde 1 movement, so that the door will be effectively held in locked position.

The improved locking means is by prefer ence applied to both sides of the pocket P and both ends of the bar B then project to engage the teeth of the door locking wheels. The ends of this bar preferably have openings O in which the bar 30 or some other bar may be carried, with its ends projecting to form handles, as seen in dotted lines in Fig.

' 8. These handles are often of assistance in swinging the door into engagement with the wheel 19.

The invention is simple and inexpensive, may be quickly and easily installed, and will be highly efficient and desirable. On account of the existing advantages for the structural features which I have disclosed, they will in most instances be followed. However, as stated, variations may be made within the scope of the invention as claimed.

I claim 1. A locking means for a dump car door, comprising a bracket for attachment to the exterior of a dump pocket of a car, a doorlocking wheel mounted on said bracket, said wheel having peripheral teeth to engage a portion of a door of said pocket and force the door tightly closed when said wheel is turned in one direction, means whereby said wheel may be so turned, a ratchet wheel r0- tat-able bodily with said door-locking wheel, and a dog mounted on said bracket, said dog and ratchet Wheel being cooperable in bold ing the door-locking wheel against retrograde turning until the car is to be dumped.

2. A locking means for a dump car door, comprising a bracket having a portion disposed in a vertical plane for mounting against the exterior ofa dump pocket of a car, said bracket having two horizontally 55 spaced arms projecting fror said vertical portion and formed with alined bearing openings whose common axis is at right angles to the aforesaid plane, a short shaft passing through said bearing openings and provided at its outer end with means whereby it may be rotated, a door-locking wheel fixedly mounted on said shaft between said arms, said arms having peripheral teeth to engage a portion of a door of said pocket and force the door tightly closed when the shaft is rotated in. one direction, a ratchet wheel secured on'said shaft, and a dog mounted on one of said arms and cooperablc with said ratchet wheel to hold said door 1 locking wheel against retrograde rotation until the car is to be dumped.

3. A locking means for a dump car door, comprising two parallel arms having attaching plates at one end, one of said arms being i offset between its ends to position its attaching plate in contact with the plate of the other arm, said plates having openings to receive fasteners for securing them against the exterior of a dump car pocket, the free ends of said arms having alined bearing openings, a short shaft passing through said bearing openings and provided at its outer end with means whereby it may be rotated, a door-locking wheel fixedly mounted on said shaft between said arms, said arms having peripheral teeth to engage a portion of a door of said pocket and force the door tightly closed when the shaft is rotated in one direction, a ratchet wheel secured on said shaft and a dog mounted on one of said arms cooperable with said ratchet wheel to hold said door-locking whee against retrograde rotation until the car is to be dumped.

4. In a locking means for a dump car door, a door-locking wheel, a short shaft b which it is carried, studs projecting outwardly from one end of said shaft and ha ing heads at their outer ends, and cams on the shaft at the inner ends of said studs, said studs being adapted for engagement by a bar used to rotate the shaft, said cams serving to force the bar outwardly toward said heads.

In testimony whereof I have hereunto afiixed my signature.

ANDREI V GERMEK.
